About Radical Bicycle Co

Welcome to Radical Bicycle Co, where we don’t just build bike frames—we craft weapons of adventure, precision-forged in the heart of the UK. Born in 2020, right when the world decided to hit the brakes, Kieran thought, "What better time to go full throttle?" After years of managing the design, supply, and installation of bespoke building finishes—and surviving his stint in the armed forces—Kieran decided it was time to combine his love for precision and chaos into one mission: creating wild mountain bike frames.

Radical Bicycle Co wasn’t backed by big investors or corporate cash; we’re 100% self-funded and proud of it. We’ve grown organically, one frame and one satisfied rider at a time. Built from the ground up in our small workshop in Shropshire, near the Welsh border, we’re surrounded by wild mountain bike trails that inspire every frame we create. Every frame is handmade, one by one, with all the love, sweat, and occasional swearing that comes with true craftsmanship. We’re not about cranking out cookie-cutter rides; we’re about building frames that scream 'Radical' in every weld, curve, and (let’s be honest) badass vibe they give off.

In 2021, we dropped our first model, The Chilli Dog, and it instantly took the mountain biking world by storm. The first prototypes not only conquered races across the UK but still continue to do so, with our very own Radical Bicycle Co race team leading the charge. It sold out before we even had the first batch made—a humble brag we’re still riding high on. Fast forward to 2023, and The Chilli Dog got nominated for Hardtail of the Year, proving it’s not just a flash in the pan but a beast of a frame that riders can’t get enough of.

And because we like to keep things as wild as our rides, we can also paint our own frames in-house using aerosol cans, giving us the freedom to create all kinds of unique and radical finishes. If you want something loud, bold, or completely out of the ordinary, we’ve got the spray cans ready.

In 2023, we kicked things up a notch. Not only do we continue to manufacture in the UK, but we also started working with a select group of carefully vetted factories overseas. This expansion allows us to offer a wider variety of products, including some budget-friendly options, without sacrificing quality or the Radical Bicycle Co spirit. Now, whether you're after a premium handmade frame or something a bit more wallet-friendly, we’ve got you covered.

Despite this growth, Radical Bicycle Co remains a small, family-oriented business to this day. We believe in keeping things personal, maintaining a tight-knit crew, and building relationships with our riders that go beyond the sale. When you buy from Radical Bicycle Co, you're not just getting a bike frame—you're joining the family.

Shipping globally from our little corner of Shropshire, our frames have touched trails from the Rockies to the Alps, and everywhere in between. Each one is designed to withstand the gnarliest of rides—if you break it, well, you're probably doing something wrong (or right?!). Either way…. We got you boo.

In 2023, Steve joined the party. Not only is he a master fabricator, but he also brings some serious expertise in carbon bike frame assessment and repair. Thanks to Steve, we had the confidence to expand our lineup to include our first carbon e-bike, the Supacat—a lightweight, rugged beast built to tackle any terrain with a boost of electric power. The Supacat isn’t just a bike, it’s a revolution in how we ride the wildest trails.

So, if you're looking for a bike frame that's as bold as your riding, welcome to the tribe. Radical Bicycle Co: making trails nervous since 2020.
